Line them up by the decimal point
Answer:
x=6
Step-by-step explanation:
Solve for x.
5x-15 = 2x+3
(Move the 2x to the other side of the equation.)
3x-15= 3
(Move the 15 to the right side of the equation.)
3x=18
(Divide both sides by 3 to isolate the variable.)
x=6

By reducing 21/30 you dived 21 and 30 by 3 and you will get 7/10. Is 7/10 larger than 2/3? If we put these fractions in decimal form we will see 7/10 turns into 0.7 and 2/3 turns into 0.667. So the answer is 21/30 is larger than 2/3.
Answer:
<em>0.15</em>
Step-by-step explanation:
Given the expression that relates the distance and the time with the expression:
d = 0.15t
d is the distance
t is the time
To determine how fast it is flying (Speed), we will need to use the formula
Speed = distance/time
s = d/t
From the given equation we can se that 0.15 = d/t
Comparing this to the general equation, we will see that s = 0.15
<em>Hence the airplane is flying at 0.15</em>
Using the Pythagorean theorem, 12^2 + 12^2 = 288 (equal lengths of a right-angle triangle). the square root of 288 is 16.9 (could be rounded to 17).
Rounding up to 17, the perimeter (P) would be 41. Without rounding, it would be 40.9.
Using the 17 measurement as the Base, the height would come out to 4.82. This can be used to find the Area, which comes out to being 41.
If you would like to double check, the measurements based on the picture are:
Sides: 12, 12, 17
Angles: 45, 45, 90
